ntfy vs Bark: Which Should You Self-Host?

Quick Verdict

ntfy is the better choice for most people because it works on every platform — Android, iOS, web, desktop, and any HTTP client. Bark is only for iOS, but if you exclusively use iPhones, Bark’s native APNs integration delivers more reliable notifications with richer iOS-specific features like critical alerts and time-sensitive delivery.

Updated February 2026: Verified with latest Docker images and configurations.

Overview

ntfy is a cross-platform push notification service that uses simple HTTP requests. Send a POST or PUT to a topic, and subscribers receive notifications on any device. Open source, UnifiedPush compatible, and backed by an active community.

Bark is an iOS-focused push notification server that routes notifications through Apple Push Notification service (APNs). It’s lightweight, simple, and designed specifically for iPhone users who want server-to-phone alerts.

Feature Comparison

Feature	ntfy	Bark
Platform support	Android, iOS, Web, Desktop, CLI	iOS only
Protocol	HTTP/WebSocket	HTTP → APNs
Authentication	Optional (user/pass, token)	Device key
UnifiedPush	Yes	No
Message priority	5 levels (min to max)	4 levels (passive to critical)
Attachments	Yes (files up to 15 MB)	No
Rich notifications	Title, tags, emojis, actions	Title, subtitle, sound, icon, URL
Scheduled delivery	Yes (delayed messages)	No
Critical alerts	No	Yes (iOS critical alerts)
Custom sounds	Limited	Full iOS sound library
End-to-end encryption	Yes (e2ee)	Yes (encrypted payload)
Web UI	Yes (full management UI)	Minimal (API-only + app)
License	Apache 2.0 / GPL 2.0	MIT
Docker image	~25 MB	~15 MB
Database	SQLite	BBolt (or MySQL)
Dependencies	None	None

Installation Complexity

Both are trivially simple to deploy:

ntfy: One container, one port (80/443), optional config file. Works immediately with zero configuration.

Bark: One container, one port (8080), zero config files. Even simpler than ntfy — no config file at all.

Both score a 10/10 on ease of deployment. The difference comes in client setup: ntfy requires installing the ntfy app and subscribing to topics, while Bark requires the Bark iOS app and registering a device key.

Performance and Resource Usage

Metric	ntfy	Bark
RAM (idle)	~30-50 MB	~20 MB
RAM (under load)	~100-200 MB	~50 MB
CPU	Very low	Negligible
Disk	~100 MB + message cache	~50 MB

Bark is marginally lighter because it does less — no message caching, no web UI, no attachment handling. Both run comfortably on any hardware, including a Raspberry Pi.

Community and Support

Aspect	ntfy	Bark
GitHub stars	20,000+	5,000+
Contributors	100+	10+
Documentation	Excellent (docs.ntfy.sh)	Good (README-based)
Community	Large, active, many integrations	Smaller, iOS-focused
Update frequency	Regular releases	Regular releases

ntfy has a significantly larger community with more third-party integrations. Bark is more niche but well-maintained.

Use Cases

Choose ntfy If…

• You need notifications on Android, desktop, or web — not just iOS
• You want UnifiedPush compatibility for other self-hosted apps
• You need file attachments in notifications
• You want scheduled/delayed message delivery
• You need a web UI for managing topics and messages
• You run monitoring tools that support ntfy natively (Uptime Kuma, Grafana, etc.)

Choose Bark If…

• You only use iPhones and want the simplest possible setup
• You need iOS critical alerts that bypass Do Not Disturb
• You want time-sensitive notification delivery via APNs
• You prefer the absolute minimal footprint (20 MB RAM, no config file)
• You value native iOS notification features (custom sounds, call-style alerts)

Final Verdict

ntfy wins for most self-hosting setups. Its cross-platform support, UnifiedPush compatibility, and ecosystem of integrations make it the universal choice. Most self-hosted monitoring and automation tools have native ntfy support — Uptime Kuma, Grafana, n8n, Home Assistant, and dozens more.

Bark is the right choice only if you’re exclusively in the Apple ecosystem and want native iOS notification features that ntfy’s iOS app can’t match. The critical alert bypass and time-sensitive delivery are genuinely useful for on-call scenarios where a push notification absolutely must break through Do Not Disturb.

Frequently Asked Questions

Can ntfy and Bark work together?

Not directly — they use different notification protocols. You’d need to send separate notifications to each. In practice, choose one: ntfy for cross-platform, Bark for iOS-only. If you have a mixed team, ntfy is the only option that covers everyone.

Does ntfy support iOS?

Yes, ntfy has an iOS app, but it uses Apple Push Notification service (APNs) through ntfy.sh or your own APNS certificate. The iOS support is functional but not as deeply integrated as Bark’s native iOS features (critical alerts, time-sensitive delivery).

How secure are push notifications with these services?

Both support self-hosting, so notifications never leave your server. ntfy supports token-based authentication and access control lists. Bark uses device-specific URLs with unique keys. Neither encrypts notification content end-to-end by default — the server can see all messages. For sensitive content, encrypt the payload at the application level before sending.

Which uses fewer resources?

Bark is lighter — ~20 MB RAM with no configuration file needed. ntfy uses ~50-100 MB RAM with a SQLite-backed message cache. Both are negligible on any modern server. Resource usage is not a meaningful differentiator between these two.

Can I use either with Home Assistant?

ntfy has a native Home Assistant integration and is the most commonly used self-hosted notification service in the Home Assistant community. Bark has no official integration — you’d need to send HTTP requests manually via the RESTful notification platform.
